[0019] The following will be combined with the attached embodiment of the utility model Figure 1-3 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] As shown in the figure, a mounting structure of an image sensor of a banknote counter includes a body 1, a lower bracket 2, a lower image sensor, an upper bracket 3 and an upper image sensor, wherein the lower image sensor is arranged in the lower bracket 2, the lower bracket 2 is fixedly connected to the body 1, the upper image sensor is arranged in the upper bracket 3, the connecting ear plates 31 formed at both ends of the upper bracket 3 are movably connected to the body 1, the end of the connecting ear plate 31 is provided with an open groove 32 matching the bearing 4 of the wheel shaft arranged on the body 1, and the bearing 4 and the open groove 32 are connected to each other. The cooperation realizes the movable connection between the connecting ear plate 31 and the body 1, and also includes a toggle plate 5 and a locking rod 6. The two ends of the toggle plate 5 are respectively connected with a locking hook plate 7 which is perpendicular to the toggle plate 5. The locking hook plate 7 is rotatably connected to the connecting ear plate 31. A torsion spring 8 is arranged between the locking hook plate 7 and the connecting ear plate 31. One end of the torsion spring 8 is fixedly connected to the locking hook plate 7, and the other end abuts against the upper bracket 3. A locking groove 71 is opened on the side end of the locking hook plate 7. The locking rod 6 is fixedly connected to the body 1 and is located on one side of the locking hook plate 7 and cooperates with the locking groove 71.

[0021] Specifically, the interlocking hook plate 7 is rotatably connected to the structure on the connecting ear plate 31:

[0022] A rotating shaft 9 is fixedly connected between the two connecting ear plates 31 . A shaft hole 72 matching the rotating shaft 9 is opened on the lock hook plate 7 . The rotating shaft 9 passes through the shaft hole 72 . The torsion spring 8 is sleeved on the rotating shaft 9 .

[0023] In the above embodiment, when the upper bracket 3 is installed on the frame so that the upper image sensor is aligned with the lower image sensor, the opening groove 32 is aligned with the bearing 4 and the bearing 4 is inserted into the opening groove 32, and the upper bracket 3 drives the toggle plate 5 and the lock hook plate 7 to swing downward along the bearing 4. When the lock hook plate 7 swings to a position in contact with the lock rod 6, the lock hook plate 7 is pushed by the lock rod 6 and swings along the rotating shaft 9 in a direction away from the lock rod 6 and twists the torsion spring 8, so that the lock hook plate 7 can swing downward against the lock rod 6, and when it swings to a position where the lock groove 71 is aligned with the lock rod 6, the lock hook Under the action of the torsion spring 8, the plate 7 swings toward the locking rod 6, so that the locking rod 6 is stuck in the locking groove 71 and is kept in the locking groove 71 under the action of the torsion spring 8, so that the upper image sensor and the lower image sensor are aligned and matched when the upper bracket 3 is installed. When the upper image sensor and the lower image sensor are disassembled for cleaning and maintenance of the upper image sensor 3, the toggle plate 5 is moved to drive the lock hook plate 7 to swing, so that the locking rod 6 is disengaged from the locking groove 71. At this time, the upper bracket 3 can be driven by the toggle plate 5 to swing and the upper bracket 3 can be removed from the bearing 4, so that the upper bracket 3 and the upper image sensor can be disassembled. Through the above-mentioned structure and method, the upper bracket 3 and the upper image sensor can be disassembled and assembled very conveniently to clean and maintain the upper image sensor and the lower image sensor, and the upper bracket 3 is fixedly installed with the cooperation of the lock hook plate 7 and the lock rod 6, so that the vibration generated when the money counter is working will not cause the lock hook plate 7 to rotate, thereby ensuring the stability of the installation of the upper bracket 3 and the upper image sensor, ensuring that the upper image sensor and the lower image sensor are stably aligned and matched, thereby ensuring the stability of the money counter when working.

[0024] Preferably, the side end of the lock hook plate 7 facing the lock rod 6 is arc-shaped, and the arc-shaped side end of the lock hook plate 7 swings more smoothly when it contacts the lock rod 6, thereby making the disassembly and assembly operation of the upper bracket 3 more convenient and smooth.

[0025] Preferably, a rotating sleeve 61 matching the locking slot 71 is provided at the position where the locking rod 6 cooperates with the locking slot 71, and the side end of the lock hook plate 7 contacts the rotating sleeve 61 during the swinging process, and the rotating sleeve 61 is driven to rotate while the lock hook plate 7 swings, so that the lock hook plate 7 contacts the rotating sleeve 61 and swings more smoothly, thereby making the disassembly and assembly operation of the upper bracket 3 more convenient and smoother.

[0026] Preferably, the cross-section of the toggle plate 5 is L-shaped, and the lock hook plate 7 is integrally formed with the vertical portion of the toggle plate 5, which strengthens the strength of the toggle plate 5 and the connection strength between the lock hook plate 7 and the toggle plate 5, thereby strengthening the strength of the lock hook plate 7 when it is hooked to the locking rod 6, and strengthening the strength of the upper bracket 3 after fixed installation.

[0027] Preferably, the lower end of the lock hook plate 7 is integrally connected with a limiting ear plate 73, and the upper bracket 3 is fixedly connected with a limiting plate 10 located below the toggle plate 5 and on the swinging path of the toggle plate 5. The limiting ear plate 73 applies a limit when the lock hook plate 7 swings in a direction close to the locking rod 6, and the limiting plate 10 applies a limit when the lock hook plate 7 swings in a direction away from the locking rod 6, so that the lock hook plate 7 is more stable when swinging, thereby making the disassembly and assembly operation of the upper bracket 3 more convenient.

[0028] Preferably, the upper end of the toggle plate 5 is integrally connected with a toggle ear plate 51 inclined to the toggle plate 5, and a handle cover 52 is fixedly connected to the toggle ear plate 51. An arrow-shaped anti-skid protrusion 521 is formed on the upper end surface of the handle cover 52. It is easier to toggle the toggle plate 5 by toggle the ear plate 51, and the anti-skid protrusion 521 indicates the toggle direction and plays a fool-proof role. The toggle plate 5 can be toggled more stably by toggling the toggle ear plate 51 through the handle cover 52, thereby making the operation of disassembling and assembling the upper bracket 3 more convenient.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
